Simple HTTP Server in node.js
Translate incomin http request into data strcuture like ring in clojure
Provide basic funcitonal programming utility creating http server
npm i @zaeny/httpbasic http server, with handler accept returning object {status, headers, body}
var { createServer, startServer, response } = require('@zaeny/http');
var mainHandler = (req, res) => ({
status: 200, headers: {}, body: 'Hello world'
});
var server = createServer({
port: 8081,
handler: (req, res) => mainHandler(req, res)
});
startServer(server);basic response with utility functions
var { createServer, startServer, response } = require('@zaeny/http');
var handler = (req, res) => response('hello world');
var server = startServer(
createServer({ port: 8081, handler: (req, res) => handler(req, res)})
);
// response json, if body isArray or isObject
var handler = (req, res) => {
return {status: 200, headers: contentType('json'), body: { is_running: true }};
}
// use response
var handler = () => response({ is_running: true}, contentType('json'));
// contentType, findFile, status, headers, created, notFound, badRequest, etc..create your own simple routing
var responseIndex = (req, res) => findFile('./index.html');
var getUser = (req, res) => response('fetch all user');
var mainHandler = (req, res) => {
let routes = {
`GET /`: responseIndex,
`GET /api/user`: getUser
}
let resolve = routes[`${req.method} ${req.path}`];
if(resolve) return resolve(req, res);
return notFound();
}
var server = server || startSever(
createServer({ port: 8081, handler: (req, res) => mainHandler(req, res)})
);usage with @zaeny/clojure.core
var {threadFirst, assoc} = require('@zaeny/clojure.core');
var info = (req, res) => response('hello world');
var server = threadFirst(
{ port: 8081, handler: info },
[createServer],
[startServer]
);advanced routing with params :id with findRotues
var routes = () => ({
'GET /api/audio/chapter/:id': 'handleGetAudioByChapter',
'GET /asset/:id': 'serveAudioAssets'
});
var resolve = {
serveAudioAssets,
handleGetAudioByChapter
}
var mainHandler = (req, res) => {
let found = findRoutes(routes(), req);
if(found && resolve[found]){
return resolve[found](req, res);
}
return notFound('404');
}
var server = threadFirst(
{ port: 8081, handler: mainHandler },
createServer,
startServer
);testing and debuging from repl, createRequest to test the handler
// create requst with headers
createRequest('GET /api/users', {headers: {'Authorization': 'Basic aziz=pass'}});
